CVE-2026-76651

A buffer

overflow vulnerability exists in the embedded HTTP service in TL-WR841N v14 when processing

multipart/form-data requests. Insufficient validation of an attacker-controlled

boundary parameter may allow a remote unauthenticated attacker to submit a

crafted request that corrupts memory by overwriting data beyond the bounds of

an internal buffer.

Successful

exploitation may result in modification or corruption of process memory,

potentially leading to undefined application behavior. Arbitrary code

execution, information disclosure, and denial-of-service conditions have not

been demonstrated.
